Apollo-client: empty headers object in afterware response

[Artem-Schander]

Hi,

I have a similar issue to #1156. But in my case the response is completely empty.
Here is my afterware:

apolloClient.networkInterface.useAfter([{
    applyAfterware({ response }, next) {
        if (process.env.NODE_ENV === 'development') {
            console.log('got new response', response);
        }
        next();
    }
}]);

Here is the real response:

Here is the console log:

BTW. I've already asked at StackOverflow

I am also having this issue, headers are completely empty.

@Artem-Schander did you create any headers on the initial request? This should be fixed by using apollo-link with the 2.0. Here is an upgrade guide if you are interested in the migration to links https://github.com/apollographql/apollo-client/blob/master/Upgrade.md#upgrading-from-custom-networkinteface-with-middleware--afterware

Additional comment here, the headers object in Chrome is actually of the type Headers. To get the values you actually need to do response.headers.get(key) . This fixed the issue for me

Thanks to both of you, but update the apollo-client to v2 is in my case not an option. I'm using vue-apollo so the dependency is ^1.0

To receive headers, you need to expose them first on the server-side. You can read more on Access-Control-Expose-Headers. If you're using cors, you may use:

app.use(cors({
  exposedHeaders: 'custom-header'
}));

I've found this information in this issue: https://github.com/apollographql/apollo-client/issues/1156
